Houston, TX- October 17, 2025 – Armexa, a leading industrial cybersecurity company specializing in secure, safe, and reliable operational technology (OT) programs, announced that John Cusimano, Chief Strategy Officer, will present a critical session at SecurityWeek’ s Industrial Control Systems (ICS) Cybersecurity Conference 2025.
The event, the largest and longest-running conference focused on industrial cybersecurity, gathers experts from across various industries, including operations and control engineers, IT professionals, government, and academics.
Armexa Presentation Details:
- Speaker: John Cusimano, Vice President of OT Cybersecurity, Armexa
- Title: Packaged Control Systems – The Achilles Heel of Most OT Cybersecurity Programs
- Date & Time: Thursday, October 30, 2025, at 10:20 AM
- Event: SecurityWeek’ s ICS Cybersecurity Conference
- Location: Intercontinental Buckhead Atlanta, GA
Mr. Cusimano’s presentation will address the often-overlooked, systemic vulnerabilities of Packaged Control Systems (PCS)—pre-engineered, plug-and-play units (such as gas compression skids and boiler control systems) that are a mainstay in industrial environments. While PCS offer benefits like rapid deployment and cost-efficiency, they are frequently the most vulnerable components in an OT network.
The session will explore why Packaged Control Systems pose a disproportionate risk to industrial cybersecurity and will use real-world examples from the oil and gas, chemical processing, and utility sectors to illustrate how they serve as entry points for threats. Attendees will gain practical insights into essential mitigation strategies, including:
- Implementing architectural segmentation and protocol hardening.
- Conducting targeted risk assessments for PCS environments.
- Applying effective vendor engagement practices to strengthen the supply chain.
